Background

The paper document is a document using paper as a carrier, such as a manuscript paper, a letter, a telegraph, a registered account, an account book, a contract, a certificate, a manuscript, a diary, a note, a book of a family tree, and an original manuscript. Paper archives have the characteristics of being easy to damage, incapable of being regenerated, needing to be kept secret and the like, and the protection and the repair of the archives are tasks and tasks which must be paid attention to in archives work.

The paper is one of four ancient inventions in China, and the paper file is generated in China (see paper literature) at first. The Donghai has already started to write documents with paper, and after Weijin, the paper documents are increasing, but official documents are still mainly simplified. By the end of Dongxing, the year of the Gongyuan 403, the Jindian dynasty, and the official documents are all written with paper. He Zhao Zhang says that ancient does not have paper, so it is simple to use and is not mainly worried about. For those who are simple in use, yellow paper is used instead. "are produced in large quantities from this paper archive. From the end of the 4 th century to the end of the 17 th century, the paper-making technology of China successively introduced into Vietnam, Korea, Japan, Arab countries, European countries, continental America and even all over the world, promoted the development of the world archive cause, and the use of paper caused the number of archives to increase sharply, taking the archives formed by Roman Church as an example: before using paper, an average of 730 files are formed every year in 11 years of 1243 + 1254 years, after using paper, an average of 5 thousands of files are formed every year in 9 years of 1294 + 1303 years, the increase is nearly 70 times, the advantages of the paper files are more, the management and the utilization are convenient, the contemporary sound image files and machine-readable files have been remarkably increased, but the paper files still occupy the main position in the total collection of archives of all countries in the world.
